Bee Body Size and Foraging Behavior Predict the Pollination Role of Bees in a Buzz-Pollinated Plant Community. [PDF]

open access: yesEcol Evol
We investigated how bee traits influence pollination success in a buzz‐pollinated plant community. Larger body size and floral sonication strongly predicted stigma contact, a proxy for pollination efficiency, while longer handling times were associated with reduced effectiveness.

Bees feeling the burn. [PDF]

open access: yesBiol Rev Camb Philos Soc
ABSTRACT Fire is a major form of environmental disturbance, and in recent years, due to anthropogenic climate change and anthropogenic land management, we are seeing increases in the frequency and intensity of fires. With bees being an important, diverse group of pollinators that is facing declines globally, understanding how they respond to fires is ...

Role of forest edges and other seminatural linear landscape features in structuring wild bee habitat connectivity in intensively managed landscapes. [PDF]

open access: yesConserv Biol
Abstract Pollinator conservation schemes typically focus on conserving existing, restoring degraded, or creating new wild bee habitats. Their effectiveness depends on dispersal corridors enabling habitat colonization by bees. However, the role of seminatural linear landscape structures (LLS) in connecting pollinator communities across intensively ...

Solitary Bees Acquire and Deposit Bacteria via Flowers: Testing the Environmental Transmission Hypothesis Using <i>Osmia lignaria</i>, <i>Phacelia tanacetifolia</i>, and <i>Apilactobacillus micheneri</i>. [PDF]

open access: yesEcol Evol
We followed a sequence of flight cage experimental steps where we allowed bees to interact with bacteria‐inoculated flowers (10:30 am), before let them interact with new uninoculated flowers (11:30 am). Later, we allowed a new set of bees (1:30 pm) to interact with these shared flowers.

First record of the neotropical subgenus Hylaeus (Gongyloprosopis) Snelling, 1982, for Brazil (Hymenoptera: Colletidae)

open access: yesEntomological Communications, 2020
We report the first record of the neotropical bee subgenus Hylaeus (Gongyloprosopis) Snelling, 1982 (Colletidae) for Brazil. Additionally, an overview of the current geographic records for the three known species of the subgenus is presented.

Hybridization between wild and cultivated potato species in the Peruvian Andes and biosafety implications for deployment of GM potatoes [PDF]

open access: yes, 2008
The nature and extent of past and current hybridization between cultivated potato and wild relatives in nature is of interest to crop evolutionists, taxonomists, breeders and recently to molecular biologists because of the possibilities of inverse gene ...
